Got off the Pred last Oct. after about 4 years since first starting.. PMR has not returned. Feeling well most of the time although a few arthritic joints bother me. Still go to aqua aerobics and Pilates ( started when I had PMR). Both help to keep supple. Do get some tired out days but have learnt to rest on those. Also have lost weight slowly over this period....now only a few pounds over pre pred weight. Look much better. Have not been actively dieting to slim, body seems to have re adjusted. Hope this gives support to others at the start of their PMR illness. I remember feeling "is this old age". Answer "no you can recover and be normal again" !!
It just takes time.
